What is this drawing? Not once in describing the shape of that mass did I shift my eyes from the model. Why? Because I wanted to be sure that nothing evaded my grasp of it... My objective is to test to what extent my hands already feel what my eyes see.
- Auguste Rodin

There is only one true thing: instantly paint what you see. When you've got it, you've got it. When you haven't, you begin again. All the rest is humbug.
- Edouard Manet
